Are you interested in working for a world top 100 University? The Department of Mechanical Engineering is inviting applications from enthusiastic and highly motivated researchers/engineers to participate in an exciting research program to study the mixing of helium with air in reactor cavities in support of the development of High Temperature Gas-cooled Reactors (HTGRs). The program is a collaboration between a number of universities and a national lab in the US, and the University of Sheffield, Science and Technology Facilities Council (STFC) and EDF Energy in the UK and is jointly funded by US Nuclear Engineering University Program (NEUP) and UK EPSRC. The US partners will carry out experimental investigations and the UK team will perform complementary numerical simulations. Working closely with a team of academics, engineers and Research Associates from the UK and the US, you will be responsible for numerical simulations using both conventional Reynolds-Averaged Navier-Stokes (RANS) CFD and high-fidelity large eddy simulation (LES) approaches. You will first study the full transient process of the blowdown from an initial pipe break to the time when equilibrium is reached using an unsteady RANS model following its validation against data obtained from the US partners. At stage 2, you will use a high fidelity well-resolved LES to investigate the fundamental flow physics underpinning the air-ingress phenomena in a HTGR. You will attend regular project meetings reporting your progress and contributing to discussions in other project areas. You will have opportunity to visit the US experimental facilities. You should hold a PhD (or have equivalent experience) in computational fluid dynamics or another equivalent discipline. Candidates should have a good background and experience in one or more of the following areas: nuclear thermal hydraulics, large eddy simulation, turbulence modelling, programming, and a good understanding of flow physics. Informal enquiries may be made to Professor Shuisheng He at We're one of the best not-for-profit organisations to work for in the UK. The University's Total Reward Package includes a competitive salary, a generous Pension Scheme and annual leave entitlement, as well as access to a range of learning and development courses to support your personal and professional development. We build teams of people from different heritages and lifestyles from across the world, whose talent and contributions complement each other to greatest effect. We believe diversity in all its forms delivers greater impact through research, teaching and student experience.
